I have tested using trusty-proposed sources and the problem is fixed.
I asked for apt-get install libhwloc-dev and it installed only 36 dependencies including ocl-icd-libopencl1 and not the nvidia packages. The versions I ended up with are:
# dpkg -l | grep hwloc
ii libhwloc-dev:amd64 1.8-1ubuntu1.14.04.1 amd64 Hierarchical view of the machine - static libs and headers
ii libhwloc-plugins 1.8-1ubuntu1.14.04.1 amd64 Hierarchical view of the machine - plugins
ii libhwloc5:amd64 1.8-1ubuntu1.14.04.1 amd64 Hierarchical view of the machine - shared libs
